BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an improved structure for a polishing machine, more particularly to an improved structure for a polishing machine of an optical disk with an enhanced efficiency.

[0003] 2. Description of the Prior Art

[0004] The optical disk is widely used at present. Since the optical disk can be used to storage large video data and digital data, it is commonly applied to such storage media as CD-ROM, Music-CD, VCD and DVD. In order to keep the optical disk on a better state for using, it is necessary to keep the reading surface of the optical disk smooth. Since the reading surface of the optical disk is a transparent plastic surface without protective capability, it is easy to scratch the reading surface during moving and placing of the optical disk. Contamination and scratch on the reading surface will affect the result negatively during reading the data, therefore it is necessary to perform a suitable clean process on the reading surface.

[0005] A simple clearing process only uses a paper or a cloth to wipe the plastic surface directly. However, this process is time and vigor consumed, and does not have good result. Additionally, when an over wiping is applied, or an abrasive paper and cloth is used to this clean process, more scratch will form on the plastic surface. As shown in FIG. 1, a polishing machine for an optical disk is developed according to the prior art. The polishing machine places the optical disk on a turntable (A) which can rotate freely, press down a bar (B) on the stand of the polishing machine to make turntable move up, and uses a polishing pad on a motor(C) to polish the optical disk. This motorized polishing machine can substantially reduce time and vigor consumed. However, the abovementioned polishing machine for the optical disk possesses the following problems:

[0006] 1. The volume of the prior art polishing machine is too large to be stored and carried personally.

[0007] 2. In order to ensure that the wiping range of the polishing pad covers the entire data zone of the optical disk, a bigger polishing pad increases the polishing time contrarily.

[0008] 3. The polishing time only can be estimated approximately during the operating of the polishing machine, therefore over polishing commonly occurred and cause the optical disk damaged permanently.

[0009] Therefore, it is an object of the present invention to provide an improved structure for a polishing machine of an optical disk which can obviate and mitigate the above-mentioned drawbacks.

SUMMARY OF THE INVENTION

[0010] The present invention is related to an improved structure for a polishing machine of an optical disk. The primary objective of the present invention is to provide a structure for a polishing machine with a precise polishing effect and higher automation to increase the quality of polishing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0020] Please refer to FIG. 2. The present invention is related to an improved structure for a polishing machine of an optical disk, which comprises a motor (2), a turntable unit (3) integrated with a housing (1), at least two polishing wheel 5) positioned on a cover which can cover up the housing (1), and a time (6).

[0021] The motor (2) is fixed in the hollow housing with a predetermined strength, the turntable unit (3) is fixed at the front of the spindle of the motor, the turntable unit (3) comprises a fixing ring (31), a circular supporting plat (32), a buffer pad (33), a positioning button (34), and a nut cover (35). The fixing ring (31) is fixed on an appropriate position at the front end of the spindle of the motor by a screw (311). The circular supporting plate (32) with a predetermined strength and the soft buffer pad (33) are positioned above the fixing ring (31) in series by the positioning button (34) with a screw bar at both ends. A nut cover (35) with turning-over bowl shape and screw inside is screwed on the positioning button (34) to fix the optical disk on the buffer pad.

[0022] Please refer to FIG. 2 with FIG. 3. The polishing wheel (5) is the main component to contact the disk surface directly to perform a clean process. A spindle shaft (511) is positioned in a base (51) of the polishing wheel (5), a screw bar (52) and a screw ring (53) is extended positioned in the center of the spindle shaft (511) on the cover (4) by tight screwing of the screw bar (52). The screw ring (53) is tightly screwed up to enhance the fixity of the polishing wheel (5) and make it freely rotatable. The surface of one of a polishing wheel (5) presses on the data zone and covers the inner half region of the optical disk. The surface of the another polishing wheel (5) covers the outer half region and the abovementioned cover (4) can cover components of the housing (1) that at least can exchange the optical disk as opened and can fix the components as closed

[0023] A timer (6) is connected to the power circuit of the motor in series to stop the motor when the motor is rotate for a predetermined time so as to precisely control the polishing time of the optical disk.

[0024] Once the present invention is fabricated by assembling the abovementioned components, the exchange of the optical disk is simply performed by disassembling the nut cover (35) and the optical disk can be fixed by screwing up the nut cover (35) later. When the cover (4) covers the housing (1), the two polishing wheel (5) is installed exactly on the abovementioned suitable position. The power of the motor is turned on to rotate turntable unit (3) and a suitable amount of powder is then added in coordination, the two polishing wheel (5) moves in parabolic to polish the surface of the optical disk, and the polishing and repairing of the plastic surface of a plastic disk is completed. As long as the set time of the timer is reached, the power of the motor is turned off and the polishing is completed.

[0025] In order to satisfy the demand of a mass production, the above-mentioned fixing ring (31), circular supporting plate (32) and positioning button (34) can be formed by a single processing, as shown in FIG. 5.

[0026] As compared with the prior art polishing machine, it is understood that the present invention has the following advantages:

[0027] 1. The present invention simplifies component, miniaturizes the volume, reduce the production cost, and promote the utility.

[0028] 2. The present invention can provide at least two polishing wheel so as to shorten the polishing time.

[0029] 3. The present invention provides an easy way to change the polishing wheel when the polishing wheel is wasted and can not be used.

[0030] 4. The present invention uses timer to precisely control the polishing time, avoid the over-polishing and cause the optical disk damaged permanently.

[0031] It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

[0032] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
